PCV on a GSXR600 w/ Full Exhaust (no o2 sensor) and not dyno tuned - worth it?

Is it worth the $$$?



My bike is quite fast already and I wouldn't need it for the speed.. would be to reduce flat spots in the power-band ideally. However my bike doesn't come stock with an o2 sensor and I don't really want to splurge for the auto-tune or a custom map.


Will the standard PC5 with an appropriate map be useful for my bike? I've spoken to racers who swear against it and don't use them for their race bikes and say it's useless.... and those that wouldn't ride without one.

I have a feeling this is going to be a 50/50 split of people telling me not to bother with it unless I'm going to get it custom-tuned.. and the other half telling me that it's essential and/or I'm damaging my engine without one.
 
^^^listen to this guy,he's right on the money...

The maps you can download from the power commander site are sh1t.The only way to do it right is to put the bike on a dyno and have it tuned by a pro.Last time I checked the cost to tune a powerc on the dyno is roughly 300.00,

Thanks - I guess I'll wait to do it right
 
No point of getting a PC or Bazaaz system unless you are going to tune it via auto-tunes or dynos. I've ridden 600s with slip ons and full systems without being tuned...once you tune, you'll never go back. The power band becomes so smooth.

A better debate would be whether or not auto tune units are useful as when I did Google for them the reviews were mixed.

Well the Auto-Tune unit is like $250 and if a custom tune is $300... then no brainer though
 
On many/most fuel injected Suzuki bikes, the stock ECU is programmable via something called a Yosh box or Teka box. The good performance shops (Rider's Choice, Pro 6, Z1 Cycletech) should have the ability to re-map the stock ECU. No Power Commander needed.

Would this be similar to an ECU Reflash?
 
Not as much tuning flexibility as a full reflash, but for a street bike, should not need it.
 
For a street bike id just buy a used slip on for a couple hundred and call it a day

I have an M4 full exhaust on the bike... why would I buy a used slip-on.. what are you talking about??


The bike currently has slight "flat spots" in the powerband at low RPM's which I would hope to correct since I am "mostly" under 6K RPM on the street.

if you want SS bikes to generate power...arent you suppose to use it in the RPM range where it's meant to be operated? like over 6k rpm?

mostly under 6k...are u crusing around town in 4th or 5th gear? assuming your doing about 80 under 6k would probably be 5th gear...

and if you say flat spots in the powerband, are you meaning that you are cracking open the throttle and getting a laggy response? if it's a yes to the above questions...your in too high gear for the speed your going and probably bogging the engine....

another solution could be a sprocket change...i had that on my old gsxr...gave the lower rpms a huge kick, and increased accerlation in general. but lowers top speed, increases rpms at the same speed compared to stock (100km 6th gear stock ran 6000rpm after sprocket change it was about 7000rpm), and made my bike slightly more twitchy

I don't want more power... perhaps you misread my first post. I was clear in stating that the bike is quite fast enough and that I don't need the speed.

Frekeyguy test-rode my bike and confirmed my suspicion that the bike tends to flat-spot in the lower RPM's. There's no lag in the throttle but there is simply a flat-spot... too lazy to google it for you.

Lastly, when I mention "under 6K" I don't mean that I'm constantly steady at 6K RPM... I tend not to get into the full power band on the street since that would be stupid.. so not sure where you're getting the idea that I'm in the wrong gear. I never made any mention of any gears relative to engine speed.

PS - Sprocket changes won't fix the flat-spotting in the power curve FYI.. which is the only solution I'm looking for. I don't need any more speed... I would like linear and smooth acceleration (which is very different from "power"/"speed")

He thinks you still have a stock system. He says get a slip on instead. If you don't care about the power I'd just put it back to stock and sell the full system.

Oh.. I figured people would take the time to read things before posting (it's right there in the title of the thread lmao).. Oh well.

Anyway - I've got the answer I needed from this thread. Thanks very much to the helpful/experienced answers. It's not worth selling the M4 for me since I love the racket. Next year I'm going to contemplate turning it into a track bike vs buying a salvaged title for conversion and figure out plans for it then. Most likely, it'll get a PCV with a custom tune.

Thanks again for all the helpful replies.

how the hell are we supposed to know you already got it? i though u were asking if the whole setup is worth getting with or without pc5/custom tune. we are not mind readers
 
the power bank on the k6/k7 gsxr 600's start around 8k rpm. Anything under 6k rpms the bike simply bogs.
